             The NPath complexity of a method is the number of acyclic execution paths through that method.
             While cyclomatic complexity counts the number of decision points in a method, NPath counts the number of
-            full paths from the beginning to the end oftheblock of the method. That metric grows exponentially, as
-            it multiplies the complexity of statements inthe same block. For more details on the calculation, see the
+            full paths from the beginning to the end of the block of the method. That metric grows exponentially, as
+            it multiplies the complexity of statements in the same block. For more details on the calculation, see the
             documentation of the [NPath metric](/pmd_java_metrics_index.html#npath-complexity-npath).
 
             A threshold of 200 is generally considered the point where measures should be taken to reduce
